Diagnostic reference levels and median doses for common clinical indications of CT: findings from an international registry
ConclusionsDRLs for CTDIvol and DLP for EUCLID clinical indications from diverse organizations were established and can contribute to dose optimization. These values were usually significantly higher in the US than in Europe.Key Points•Registry data were used to create benchmarks for 10 common indications for CT identified by the European Society of Radiology.•Observed US radiation doses were higher than European for 9 of 10 indications (except chronic sinusitis).•The presented diagnostic reference levels and median doses highlight potentially unnecessary variation in radiation dose.

CT diagnostic reference levels based on clinical indications: results of a large-scale European survey
ConclusionsThis is the first study reporting on feasibility of establishing CT DRLs based on CI using European data. Resulting values will serve as a baseline for comparison with local radiological practice, national authorities when DRLs are set/updated, or as a guideline for local DRL establishment.Key Points•First study reporting on the feasibility of establishing CT diagnostic reference levels based on clinical indication using data collected across Europe.•Only one-fourth of the hospitals had CT machines less than 5 years old.•Large dose variations were observed among hospitals and CT protocols were quite differ...

Endovascular aspiration to treat acute ischemic stroke caused by embolic carcinoma.
We report a rare case of large-cell, high-grade neuroendocrine lung cancer embolus occluding the basilar artery, which likely detached into the bloodstream from the lung after intruding into a pulmonary vein. The embolus was treated with endovascular aspiration, and achieved modified Thrombolysis In Cerebral Infarction 2c revascularization. After initial neurological recovery, the patient suffered respiratory arrest and support was withdrawn 48 h later. We discuss the tumor characteristics and implications for treatment of acute ischemic stroke in patients with cancer diagnoses. PMID: 30786802 [PubMed - as supplied by publisher]

Image-based screening.
Abstract Screening is a special issue in medical questions concerning disease prevention. Preconditions for screening are clearly defined by the World Health Organization. High prevalence, effectiveness of therapy, availability of accepted test procedure and consensus concerning the economic concerns are necessary for successful implementation of a screening program. Preventive diagnostic studies can only be understood if one is familiar with the statistical terms sensitivity, specificity, prevalence, incidence and bias (especially overdiagnosis and lead time bias). Aspects of radiation protection are especially...

A potential role of ECG-Gated CT for the diagnosis of pulmonary vein thrombus; an illustrative case report
The presence of tumor thrombus in patients with lung cancer confers a risk of stroke and other end organ ischemic events. This case highlights a potential role for ECG-Gated Computed Tomography (ECG-CT) in the diagnosis of this pathologic process. In this case pulmonary vein thrombus was definitively identified by an ECG-CT following discordant results between Computed Tomography (CT) and Transthoracic Echocardiogram (TTE). In addition, this case demonstrates how management decisions are affected by physician accessibility to and familiarity with specific imaging tests.
